Sieve scripts, and the sieve library (sieve_interface.h) deal with UTF-8 and UTF-8 only. lmtpd needs to translate from UTF-8 to mUTF7 when performing a fileinto so that users don't need to see the yuckiness that is mUTF7.

adding Mark Keasling, who showed interest in fixing.

the method we discussed was to add a function call to mboxname.c to convert UTF-8 to mUTF7. it might also validate the mailbox name at that time.

(From update of attachment 112) two things: i don't understand when a caller would want to pass NULL as the first parameter to mboxname_utf8toutf7(); it looks like it'll inevitably return NULL in that case and no useful work will be performed.

• i just updated lib/imapurl.c with comments and checking for overlong utf-8 sequences. it might be of interest.

Add code to do UTF-8 to mUTF-7 conversion at script compile time, rather than at execution time. Probably needs some further testing.
